无法删除符号链接

Question

我不小心颠倒了我的 ln 的参数并调用了：

ln -s my_link my_dir

其中 my_dir 已经存在而 my_link 不存在。我删除了 my_dir，但无法删除 my_link。

如果我 ls -l my_link 的父目录，我会得到 2 个不同响应中的 1 个，或者：

l????????? ? ?       ?       ?            ? my_link

或者：

lrwxrwxrwx 1 username username 8 Mar 20 16:34 my_link

如果我打电话，rm my_link我会得到：

rm: cannot remove `my_link': Not a directory

而且，我不确定它是否相关，但 my_link 驻留在网络安装的驱动器上。

有谁知道我在这里做了什么，以及如何删除断开的链接？

编辑： 我查看了我的 bash_history 并找到了我运行的命令。看起来我实际上并没有删除 my_dir，它只是不复存在了。我运行了几个版本的错误 ln 命令。

这是我在删除错误之前运行的未经编辑的命令列表：

ln -s test_dir ~/netdrive/test_dir/
ln -s test_dir ~/netdrive/test_dir
ln -s test_dir/ ~/netdrive/test_dir/

您会注意到我已经取消了 my_link 和 my_dir。实际名称都是 test_dir，这可能导致了我的一些困惑（我希望永远不要再犯这个错误）。

所以现在不再有目录 ~/test_dir，有目录 ~/netdrive/test_dir/ 并且有断开的链接 ~/netdrive/test_dir/test_dir

这是我试图删除的最后一个。我希望更多的是澄清而不是使水变得浑浊。

编辑2：

我的操作系统是 CentOS，我很确定网络驱动器是 Samba。

这是输出的最后几行strace -f -v unlink test_dir：

Answer 1

确保您不包括尾随 /

即rm my_link不是rm my_link/

尾随 / 表示您要删除符号链接之外的内容

Answer 2

试着做：

rm -rf my_link

我在本地文件系统和网络文件系统 (NFS) 上测试了它，它工作正常。
